Does this get easier?

I lost my very wanted baby boy, who my husband I tried really hard for, about three months ago. I still grieve my little Eli everyday. As it gets closer and closer to my old due date, I get so much sadder. Not to mention, my sister-in-law announced a pregnancy with a baby boy very soon after, and she’s getting so much support when nobody was really there for me other than my own little sister and my husband. I’m trying so hard not to but I feel so resentful and sad and angry. It feels so unfair and I pray everyday for things to get easier but I feel this void in my soul.
